Taking the glass manufacturing facility 100 of the specific example shown in fig. 1 as an example, it is a one-kiln five-line facility, comprising a main line 120, two first branch line lines 130, and two second branch line 160. The glass production apparatus 100 is capable of simultaneously producing glass of different thicknesses, different colors or functions. The production glass types are exemplified in table 1.
TABLE 1
Here, the thickness T is a thickness of the glass product on the main line production line 120, and the thickness X is a thickness other than the thickness T.
Taking the production of the second branch line 2 as an example, the examples of glass production thereof are listed in table 2.
TABLE 2
Taking the production of the first branch line 1 as an example, the examples of glass production are listed in table 3.
TABLE 3
Compared with the mode of constructing a production line of colored glass or functional glass, the glass production equipment 100 and the glass production method share one melting furnace 110, and a converging device 131 and an auxiliary melting furnace 132 are arranged in a first branch production line 130, so that the design production capacity of the melting furnace 110 is not limited to the yield of the colored glass or the functional glass, and the production capacity of the colored glass or the yield of the functional glass is increased on the basis of the existing white glass production line, thereby improving the production capacity of the glass production line and reducing the production cost of the colored glass or the functional glass. In addition, the glass melt formed by the glass colorant and/or the glass auxiliary material in the auxiliary melting furnace 132 is fed into the confluence device 131 to be mixed, thereby avoiding the problems of difficulty in melting, color unevenness, generation of bubbles, and the like caused by directly adding the colorant or the auxiliary agent.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
